PRESERVATION OF VISCERA AXD OTHER ARTICLES 67 3. The spleen. If the spleen is very large a portion only need be preserved. 4. One kidney. 5. The upper part of the small intestine with its contents. According to the rules oŁ the U.P. Government for transmitting viscera and other articles to the Chemical Examiner for analysis the stomach and its contents are to "be preserved in one bottle, and pieces of the liver, spleen, kidney and of the upper part of the small intestine, in another bottle, but it is advisable to preserve the stomach and its contents together with a piece of the upper part of the small intestine in one bottle, and pieces of the liver, spleen and kidney in another bottle. In the case of infants one bottle is quite sufficient. These viscera are to be preserved in rectified spirit except in cases of suspected poisoning by alcohol, phosphorus, paraldehyde, acetic acid or carbolic acid and other drugs of the phenol group when a saturated solution of common salt is to be employed.6 The pieces of viscera should be slashed or cut into small pieces to ensure penetration of the preservative used. It should be remembered that the quantity of the rectified spirit or the saturated solution of common salt should be equal to that of the viscera in bulk. The viscera and rectified spirit or saturated solution of common salt together should not fill the bottles, but only reach to two-thirds of their height, in order to diminish the risk of the bottles bursting in case any gas of decomposition is given off.7 The stoppers of the bottles should be treated with motor grease, vaseline or any other suitable grease, to prevent them sticking, and should be securely tied in position by tape or string, the ends of which should be sealed in such a manner that the bottles could not be opened without breaking the seals. A label containing the name of the deceased and the viscera should be pasted on to each bottle. A sample of the preservative used—either the rectified spirit or the saturated solution of common salt—should always be preserved in a separate phial for chemical analysis, unless the preservative is supplied from the Chemical Examiner's office. Before despatch to the Chemical Examiner each bottle should be put into the cardboard case in which it was issued from the Chemical Examiner's office. The number stencilled on the cardboard case should be the same as that of the bottle. The cardboard case should be so securely tied up by the pieces of tape attached to its sides and sealed that it would not be possible to open the cardboard case without breaking the seals. The cardboard case should then be placed in a wooden box, called a standard pattern box, which is also supplied by the Chemical Examiner. The box has a pent-roof shape, is furnished with a door at the side and is lined inside with cushions which press against the bottle firmly on all sides, so that no further packing material is necessary. A bigger wooden box divided into two compartments is also supplied so that it can hold both the bottles. The door of the box has a lock whose key remains permanently with the Civil Surgeon. A duplicate key is kept in the Chemical Examiner's office. A serial number is marked on each box and also on the key. This number should be quoted in the letter informing the Chemical Examiner of the despatch of the parcel. After locking the door of the box a piece of tape should be passed across the key- hole and sealed in the depression made in the wood near the keyhole. The address label should be pasted to the door of the box in such a position as to cover the keyhole. On this label the number and date of the letter advising despatch to the Chemical Examiner should always be inserted to 6. The UJ>.
